In a circle we have :
Formula for the Arc length = Ф * R , Ф in radians
or = Ф * 2π /360° * R if Ф is in °.
Given Arc length = Ф/360° * 2 * π * R
It is same as the formula.
We need the data of length of arc and angleФ, to find Radius R.

Yeah but what is the final formula of r after substitution...
I need help with the substitution

Heya user,
given, minor ⌒ = θ / 360 * 2πradius
=> minor ⌒ / [ ( θ / 360 ) ( 2π ) ] = radius
=> Radius = minor ⌒ / [ ( θ / 360 ) ( 2π ) ]
given, minor ⌒ = θ / 360 * 2πradius
=> minor ⌒ / [ ( θ / 360 ) ( 2π ) ] = radius
=> Radius = minor ⌒ / [ ( θ / 360 ) ( 2π ) ]
thank u so much
Honestly I can't thank you enough!! I hv my math exam tmrw and ur such a life saver... tysm fam
Np... All the best
